Engine cover assembly feature

ABSTRACT

An engine cover having a feature that macro aligns the engine cover to the engine to quickly orientate the engine cover for correct assembly is provided. The features allow the installer to align the engine cover by touch. The locating lip is a macro feature formed integrally with the engine cover. The system includes an engine cover, a body attached to and extending from the engine cover. The body has an outer surface and an aperture for receiving a mechanical fastener. The aperture is formed through the outer surface. A locating lip extends outwardly from the outer surface. A doghouse feature may be formed on the engine cover. The body may be in the shape of an elongated tower that is attached to and extends from the doghouse feature. The locating lip is defined by a wall. The wall may be a ring-shaped wall or may be a semi-circular wall.

TECHNICAL FIELD

The disclosed inventive concept relates generally to engine covers for vehicle engines. More particularly, the disclosed inventive concept relates to engine covers having macro alignment features formed thereon that allow the installer to readily orient the engine cover for correct installation.

BACKGROUND OF THE INVENTION

Vehicle engine compartments as are known today provide only a relatively small space in which to package the vehicle engine and its peripheral components. Today's vehicle engineers and designers are challenged by requirements relating to functionality, serviceability and aesthetics. In addition, vehicle engineers and designers must also respond to manufacturing and assembly costs which are in addition to the need to continually reduce vehicle weight.

One component that has become increasingly popular in the vehicle engine compartment is the engine cover. The engine cover serves the dual-purpose of enhancing the overall appearance of the engine compartment and reducing engine noise. The engine cover may be attached to either an engine component or a powertrain component or, in the case of a front wheel drive vehicle, may be attached to both engine and powertrain components.

The engine cover is typically cast or molded from a polymerized material. However, known engine covers lack any visual reference as to how the engine cover should be installed relative to the engine. Accordingly, during vehicle assembly, it is possible for installers to misassemble the engine cover thus resulting in an incorrectly fitted engine cover.

Thus a new approach to attaching an engine cover to a substrate such as an engine component or a powertrain component is needed to address the problems associated with known arrangements.

SUMMARY OF THE INVENTION

The disclosed inventive concept overcomes the challenges faced by known engine cover arrangements by providing an engine cover having a feature that macro aligns the engine cover to the engine to quickly orientate the engine cover for correct assembly. The features allow the installer to align the engine cover by touch. The locating lip is a macro feature formed integrally with the engine cover.

The system of the disclosed inventive concept includes an engine cover, a body attached to and extending from the engine cover, the body having an outer surface and an aperture for receiving a mechanical fastener, the aperture being formed through the outer surface. A locating lip extends outwardly from the outer surface.

A doghouse feature may be formed on the engine cover. The body may be in the shape of an elongated tower that is attached to and extends from the doghouse feature.

The locating lip is defined by a wall. The wall may be ring-shaped or may be a semi-circular wall. The semi-circular wall is characterized as an eyebrow feature because of its shape.

As an alternative arrangement, the alignment feature may be associated with an oil cap hole formed in the engine cover.

The above advantages and other advantages and features will be readily apparent from the following detailed description of the preferred embodiments when taken in connection with the accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

In the following figures, the same reference numerals will be used to refer to the same components. In the following description, various operating parameters and components are described for different constructed embodiments. These specific parameters and components are included as examples and are not meant to be limiting.

Referring to FIG. 1, a perspective view of a preferred embodiment of the engine cover alignment feature of the disclosed inventive concept is illustrated. Referring to FIG. 2, a sectional view of the alignment feature of FIG. 1 is illustrated attached to a substrate. Reference will now be made to both of these figures.

A doghouse 10 of an engine cover 12 is illustrated. A fastener tower 14 extends from and is preferably integrally formed with the engine cover 12 and includes a fastener hole 16 through which an engine cover fastener, such as shoulder bolt 18, is provided to attach the engine cover 12 to the underlying substrate, such as an engine component 20. The substrate, in this case the engine component 20, includes a screw boss 22 formed on the engine component 20. Alternatively, the engine cover 12 may be attached to a powertrain component or, in the case of a front wheel drive vehicle, may be attached to both engine and powertrain components.

The shape and size of the engine cover 12 are shown for illustrative purposes only and are not intended as being limiting. In addition, while the substrate is illustrated as being an engine component, it is to be understood that the substrate may be attached, either alternatively or additionally, to the vehicle's powertrain.

The fastener tower 14 includes an alignment feature 24 having the general shape of an eyebrow. The eyebrow-shaped alignment feature 24 allows the installer to readily position the engine cover 12 with respect to the screw boss 22 of the engine component 20 or other substrate.

FIG. 3 illustrates an alternative embodiment of the macro alignment feature of the disclosed inventive concept. In this figure, a fastener tower 30 extends from an engine cover 32. The fastener tower 30 includes a fastener hole 34 through which an engine cover fastener, such as the shoulder bolt of FIG. 2, is provided to attach the engine cover 32 to the underlying substrate, such as the engine component of FIG. 2.

The shape and size of the engine cover 32 are shown for illustrative purposes only and are not intended as being limiting. In addition, while the substrate is suggested as being an engine component, it is to be understood that the substrate may be any other component of the engine to which the engine cover 12 may suitably be attached.

The fastener tower 30 includes an alignment feature 36 having the general shape of an eyebrow. The eyebrow-shaped alignment feature 36 allows the installer to readily position the engine cover 32 with respect to the screw boss of the substrate.

FIG. 4 illustrates an alternative alignment arrangement for the engine cover according to the disclosed inventive concept. Particularly, FIG. 4 provides an alignment feature for fitting an engine cover to a substrate having an oil cap hole for placement over the engine's oil fill hole.

Referring to FIG. 4, an engine cover 40 includes a hole 42 for the engine oil cap (not shown). A raised peripheral wall 44 is formed along the periphery of the hole 42 to enhance structural integrity and to provide a more finished look to the engine cover 40.

An eyebrow alignment feature 46 extends from a portion of the raised peripheral wall 44. The eyebrow alignment feature 46 may extend along the raised peripheral wall 44 to a greater or lesser degree than that shown.

The eyebrow alignment feature 24 of FIGS. 1 and 2, the eyebrow alignment feature 36 of FIG. 3, and the eyebrow alignment feature 46 of FIG. 4 provide a first general approach to solving the problem of aligning an engine cover to a substrate such as an engine component as is known. As a further approach, the alignment feature does not necessarily need to be limited to such eyebrow configurations, but may provide an alignment feature that is a full ring. This approach is illustrated in FIG. 5 in which a full ring or circle guide is provided to the doghouse of an engine cover.

Particularly, and referring to FIG. 5, an engine cover 50 includes a doghouse 52 formed thereon. An alignment feature 54 is formed on the doghouse 52. A fastener hole 56 for a fastener (not shown) is formed in the alignment feature 54. A peripheral elevated ring 58 defines the alignment wall of the alignment feature 54.

The disclosed inventive concept as set forth above overcomes the challenges faced by known engine covers for alignment onto an engine substrate, such as an engine component or powertrain component.
